Hi all,

=20

So I have a question about iteration.  Here's some code I saw on Ruby on
Windows:

=20

inbox.Items.each do |message|
    message.Attachments.each do |attachment|
        filename =3D "c:\\attachments\\#{attachment.FileName}"
        attachment.SaveAsFile(filename)          =20
        File.delete(filename) if File.size(filename) < 500000
    end
end

=20

What I find troubling is 'message,'.  How do we know the variable to
iterate over?  I have the same issue with VBScript, where the same code
would be:

=20

For each objMessage in colItems

                Etc.

Next

=20

The thing that's bothering me is where people decide the thing to
iterate over.  How do you decide what to put between the pipes | |?

=20

Sorry for the retarded question,
